Description

Die Erfindung betrifft ein Verfahren zur Befestigung mehrerer Werkstücke mittels eines hohlen Nietelements.The invention relates to a method for fastening a plurality of workpieces by means of a hollow rivet element.

Zum Verbinden von mehreren Werkstücken ist eine Verbindung durch Niete eine alte und zuverlässige Methode. Für Situationen, in denen nur ein einseitiger Zugang zur Verbindungsstelle möglich ist, sind Blindniete bekannt. Bei Blindnieten wird nach Einführen des Niets in die Befestigungsöffnungen der zu verbindenden Werkstücke ein Nietdorn gezogen, sodass sich der Niet auf der nicht zugänglichen Rückseite der Werkstücke plastisch verformt und diese dauerhaft verbindet. Der Nietdorn reißt nach der Verbindungsausbildung ab.To join multiple workpieces, connecting with rivets is an old and reliable method. For situations in which only one-sided access to the joint is possible, blind rivets are known. In the case of blind rivets, after the rivet has been inserted into the fastening openings of the workpieces to be joined, a rivet mandrel is pulled so that the rivet plastically deforms on the inaccessible rear side of the workpieces and connects them permanently. The rivet mandrel breaks off after the connection training.

Blindniete sind aufwendig in der Produktion und weisen deswegen im Vergleich zu anderen Nieten relativ hohe Stückkosten auf. Zudem ist ein nachträgliches Anziehen der Verbindung ist nicht mehr möglich.Blind rivets are expensive to produce and therefore have relatively high unit costs compared to other rivets. In addition, a subsequent tightening of the connection is no longer possible.

Die US 2 445 803 A bildet die Basis für den Oberbegriff des Anspruchs 1 und beschreibt ein Verfahren zum Vernieten mehrerer Werkstücke mittels eines hohlen Nietelementes, das durch das Einbringen eines Fluids unter Hochdruck umgeformt wird. Bei diesem Verfahren wird eine Flüssigkeit in den Hohlraum des Nietelementes eingefüllt und mit einem bestimmten Druck beaufschlagt. Im Laufe des Verfahrens wird der Druck mehrmals verringert und anschließend wieder auf den bestimmten Druck erhöht, um Teile des Nietelementes kalt zu verfestigen.The US 2 445 803 A forms the basis for the preamble of claim 1 and describes a method for riveting a plurality of workpieces by means of a hollow rivet element, which is formed by the introduction of a fluid under high pressure. In this method, a liquid is filled in the cavity of the rivet and subjected to a certain pressure. In the course of the process, the pressure is reduced several times and then increased again to the specified pressure to cold-strengthen parts of the rivet element.

Die US 6 301 766 B1 zeigt ebenfalls ein Verfahren zum Befestigen mehrerer Werkstücke mittels eines Nietelementes, wobei das Nietelement hohl ist. Das Nietelement wird dadurch umgeformt, dass ein unter Druck stehendes Fluid in den Hohlraum eingebracht wird.The US 6 301 766 B1 also shows a method for securing a plurality of workpieces by means of a rivet element, wherein the rivet element is hollow. The rivet element is reshaped by introducing a pressurized fluid into the cavity.

Auch die US 2 562 721 A offenbart ein Verfahren zur Befestigung mehrerer Werkstücke mittels eines hohlen Nietelementes, bei dem das Nietelement dadurch umgeformt werden kann, dass ein Fluid unter Hochdruck in den Hohlraum des Nietelementes eingebracht wird.Also the US 2 562 721 A discloses a method for securing a plurality of workpieces by means of a hollow rivet element, wherein the rivet element can be reshaped by introducing a fluid under high pressure into the cavity of the rivet element.

Die DE 689 584 C zeigt ebenfalls ein Verfahren zur Befestigung von Werkstücken mittels hohlen Nieten, wobei die unter Hochdruck eingeführte Flüssigkeit nach der Verformung im Niet verbleibt.The DE 689 584 C also shows a method for fixing workpieces by means of hollow rivets, wherein the introduced under high pressure liquid after deformation remains in the rivet.

Die US 2 492 590 A beschreibt eine Verfahren zum Befestigen mehrerer Werkstücke mittels hohler Nieten, wobei das Schließende der Nieten durch das Einbringen eines Fluids unter Druck verformt wird.The US 2 492 590 A describes a method for securing multiple workpieces by means of hollow rivets, wherein the closing end of the rivets is deformed by the introduction of a fluid under pressure.

Entsprechend ist es die Aufgabe der Erfindung, ein Verfahren zur Befestigung mehrerer Werkstücke bereitzustellen, das kostengünstig ist.Accordingly, it is the object of the invention to provide a method for fixing a plurality of workpieces, which is inexpensive.

Die Aufgabe wird gelöst durch ein Verfahren gemäß Anspruch 1. Durch die Erfindung ist es möglich, das Nietelement auf einfache Weise zur Befestigung mehrerer Werkstücke zu verwenden. Insbesondere sind keine komplexen Strukturen am Nietelement selber notwendig, sodass die Stückkosten drastisch gesenkt werden können. Außerdem wird die Klemmlänge des Nietelements durch die Auswahl des Drucks bestimmt. Dadurch ist es möglich, dass baugleiche Nietelemente für verschiedenartige Verbindungen herangezogen werden können, sodass die Stückkosten der Nietelemente weiter verringert werden können. Weiterhin ist erfindungsgemäß vorgesehen, dass das Fluid, nach der Verformung des Nietelements, mit einem erhöhten Druck erneut in den Hohlraum eingebracht wird, um die Verbindung der beiden Werkstücke nachzuziehen.Beispielsweise wird das Nietelement und/oder das Fluid vor dem Einbringen des Fluids erwärmt, wodurch der zur Verformung notwendige Druck des Fluids reduziert werden kann, um die Kosten des Verfahrens weiter zu senken.The object is achieved by a method according to claim 1. By the invention it is possible to use the rivet element in a simple manner for fastening a plurality of workpieces. In particular, no complex structures on the rivet element itself are necessary, so that the unit costs can be drastically reduced. In addition, the clamping length of the rivet element is determined by the selection of the pressure. This makes it possible that identical rivet elements can be used for various compounds, so that the unit cost of the rivet elements can be further reduced. Furthermore, according to the invention, the fluid, after the deformation of the rivet element, is reintroduced into the cavity at an elevated pressure in order to retighten the connection of the two workpieces. For example, the rivet element and / or the fluid is heated prior to introduction of the fluid, whereby the pressure of the fluid necessary for the deformation can be reduced in order to further reduce the costs of the process.

Vorzugsweise wird das Fluid aus dem Hohlraum entfernt oder entweicht, nachdem die gewünschte Verformung des Nietelements erzielt wurde. Auf diese Weise ist es möglich, auch fluidempfindliche Werkstücke mittels des erfindungsgemäßen Verfahrens zu verbinden.Preferably, the fluid is removed from the cavity or escaped after the desired deformation of the rivet element has been achieved. In this way it is possible to connect fluid-sensitive workpieces by means of the method according to the invention.

In einer Ausgestaltung der Erfindung sind der Druck und die Temperatur des Fluids an die gewünschte Klemmlänge des Nietelements angepasst, sodass die Klemmlänge des Nietelements durch die Auswahl des Drucks und der Temperatur bestimmt werden kann. Auf diese Weise ist es möglich, dass baugleiche Nietelemente für verschiedenartige Verbindungen herangezogen werden können, sodass die Stückkosten der Nietelemente weiter verringert werden können.In one embodiment of the invention, the pressure and the temperature of the fluid are adapted to the desired clamping length of the rivet element, so that the clamping length of the rivet element by the selection of the pressure and Temperature can be determined. In this way, it is possible that identical rivet elements can be used for various compounds, so that the unit cost of the rivet elements can be further reduced.

In einer Ausführungsvariante wird ein Nietelement verwendet, mit einer hohlen, zylinderförmigen Hülse, die ein Setzende, ein Schließende und einen sich zwischen dem Setzende und dem Schließende erstreckenden Schaft aufweist, und einem Kragen, der am Setzende an der Hülse angeordnet ist, wobei die Hülse am Setzende offen und am Schließende geschlossen ist, wobei der Schaft und/oder das Schließende wenigstens einen Formabschnitt aufweist, der verglichen mit anderen Abschnitten des Schafts und/oder des Schließendes eine andere Verformbarkeit aufweist. Durch die Ausbildung eines Formabschnittes mit veränderter Verformbarkeit ist es möglich, die Form des Schließendes nach dem plastischen Verformen auf einfache Weise zu beeinflussen.In one embodiment, a rivet element is used, with a hollow, cylindrical sleeve having a seating end, a closing end and a shaft extending between the seating end and the closing end, and a collar disposed at the seating end of the sleeve, wherein the sleeve is open at the set and closed at the closing end, wherein the shaft and / or the closing end has at least one mold portion having a different deformability compared to other portions of the shaft and / or the closing end. By forming a mold section with modified deformability, it is possible to influence the shape of the closing end after the plastic deformation in a simple manner.

Vorzugsweise wird der Formabschnitt durch wenigstens einen Abschnitt gebildet, der eine Wandstärke aufweist, die sich von der Wandstärke des Schafts und/oder des Schließendes außerhalb des Formabschnittes unterscheidet, sodass die Ausbildung des Formabschnittes einfach und kostengünstig zu realisieren ist.Preferably, the mold portion is formed by at least one portion having a wall thickness which differs from the wall thickness of the stem and / or the closing end outside of the mold portion, so that the formation of the mold portion is easy and inexpensive to implement.

Beispielsweise wird der Formabschnitt durch Schwächung des Schaftes und/oder des Schließendes, insbesondere durch eine Einkerbung, gebildet, wodurch eine einfache und kostengünstige Möglichkeit der Bildung eines Formabschnittes gegeben ist.For example, the mold section is formed by weakening of the shank and / or the closing end, in particular by a notch, whereby a simple and cost-effective way of forming a mold section is given.

Der Kragen und die Hülse können einstückig ausgeführt sein, wodurch die Herstellungskosten des Nietelements weiter verringert werden.The collar and the sleeve can be made in one piece, whereby the manufacturing cost of the rivet element can be further reduced.

In einer Ausführungsform der Erfindung wird zum Lösen der Nietverbindung das Fluid erneut unter Hochdruck in den Hohlraum des Nietelements eingebracht, wobei der Druck so hoch gewählt ist, dass das plastisch verformte Schließende des Nietelements abreißt. Auf diese Weise ist es möglich, die Verbindung der mehreren Werkstücke mit dem gleichen Werkzeug zu lösen, das auch zum Verbinden der Werkstücke verwendet wurde.In one embodiment of the invention, the fluid is again introduced under high pressure into the cavity of the rivet element to release the rivet connection, wherein the pressure is selected so high that the plastically deformed closing end of the rivet element tears off. In this way, it is possible to solve the connection of the multiple workpieces with the same tool that was also used to connect the workpieces.

Weitere Merkmale und Vorteile der Erfindung ergeben sich aus der nachfolgenden Beschreibung sowie aus den beigefügten Zeichnungen, auf die Bezug genommen wird. In den Zeichnungen zeigen:

  • Figur 1 ein Nietelement zum Verbinden mehrerer Werkstücke nach Schritt a) eines erfindungsgemäßen Verfahrens,
  • Figur 2 das Nietelement nach Figur 1 beim Durchführen der Schritte b) und c) des erfindungsgemäßen Verfahrens,
  • Figur 3 das Nietelement nach Figur 1 nach Durchführung des erfindungsgemäßen Verfahrens, und
  • Figur 4 das Nietelement nach Figur 1 nachdem es erfindungsgemäß gelöst wurde.
Further features and advantages of the invention will become apparent from the following description and from the accompanying drawings, to which reference is made. In the drawings show:
  • FIG. 1 a rivet element for connecting a plurality of workpieces after step a) of a method according to the invention,
  • FIG. 2 the rivet element after FIG. 1 when performing steps b) and c) of the method according to the invention,
  • FIG. 3 the rivet element after FIG. 1 after carrying out the method according to the invention, and
  • FIG. 4 the rivet element after FIG. 1 after it has been solved according to the invention.

In Figur 1 ist eine Verbindungsstelle 10 zwischen zwei Werkstücken 12, 14 im Schnitt dargestellt. Die Werkstücke 12, 14 weisen jeweils eine miteinander fluchtende Öffnung 16 auf, durch die sich ein Nietelement 18 erstreckt.In FIG. 1 is a junction 10 between two workpieces 12, 14 shown in section. The workpieces 12, 14 each have an aligned opening 16 through which a rivet element 18 extends.

Das Nietelement 18 weist eine zylinderförmige Hülse 20 und einen Kragen 22 auf, und es kann aus einem Metall oder einem Kunststoff hergestellt sein.The rivet element 18 has a cylindrical sleeve 20 and a collar 22, and it may be made of a metal or a plastic.

Die zylinderförmige Hülse 20 ist zum Beispiel kreiszylinderförmig und weist ein Setzende 24 und ein Schließende 26 auf, zwischen denen sich ein Schaft 28 erstreckt.The cylindrical sleeve 20 is for example circular cylindrical and has a seating end 24 and a closing end 26, between which a shank 28 extends.

Die Hülse 20 ist hohl ausgeführt, wobei sie am Setzende 24 offen ist und am Schließende 26 geschlossen ist, sodass das Nietelement 18 einen einseitig geöffneten Hohlraum 29 ausbildet.The sleeve 20 is made hollow, being open at the setting end 24 and closed at the closing end 26, so that the rivet element 18 forms a cavity 29 which is open on one side.

Der Schaft 28 kann einen Formabschnitt 30 haben, der sich in Umfangsrichtung vollständig um die Hülse 20 erstreckt.The shaft 28 may have a molding portion 30 that extends circumferentially completely around the sleeve 20.

Der Formabschnitt 30 weist verglichen mit anderen Abschnitten des Schaftes 28 eine andere Verformbarkeit auf. Beispielsweise ist die Verformbarkeit im Formabschnitt 30 gegenüber der Verformbarkeit des restlichen Schaftes 28 vergrößert.The mold section 30 has a different deformability compared to other sections of the shaft 28. For example, the deformability in the mold section 30 compared to the deformability of the remaining shaft 28 is increased.

Die unterschiedliche Verformbarkeit des Formabschnitts 30 kann durch einen Abschnitt gebildet werden, der eine Wandstärke aufweist, die sich von der Wandstärke des Schaftes 28 außerhalb des Formabschnitts 30 unterscheidet.The different deformability of the mold section 30 can be formed by a section having a wall thickness which differs from the wall thickness of the shaft 28 outside the mold section 30.

Auch kann der Formabschnitt 30 durch eine Schwächung des Schaftes 28, insbesondere durch Einkerbungen, gebildet werden.Also, the mold portion 30 by a weakening of the shaft 28, in particular by notches, are formed.

Selbstverständlich kann der Formabschnitt 30 am Schließende 26 der Hülse 20 vorgesehen sein, wobei das oben Gesagte auf das Schließende 26 entsprechend Anwendung findet. Zum Beispiel unterscheidet sich die Verformbarkeit des Formabschnittes dann von der Verformbarkeit des restlichen Schließendes 26.Of course, the mold portion 30 may be provided at the closing end 26 of the sleeve 20, wherein the above applies to the closing end 26 applies accordingly. For example, the deformability of the mold section then differs from the deformability of the remaining closing end 26.

Denkbar ist es selbstverständlich auch, dass der Formabschnitt 30 sich nicht vollumfänglich um den Umfang der Hülse 20 erstreckt, sondern in Umfangsrichtung nur abschnittsweise.It is also conceivable, of course, that the mold section 30 does not extend completely around the circumference of the sleeve 20, but only in sections in the circumferential direction.

Der Formabschnitt 30 kann auch durch einen Abschnitt gebildet werden, der eine Verfestigung aufweist, die sich von der Verfestigung des Schaftes 28 oder des Schließendes 26 unterscheidet.The molding portion 30 may also be formed by a portion having a solidification that differs from the solidification of the shank 28 or the closing end 26.

Der Kragen 22 ist am Setzende 24 der Hülse 20 angeordnet und kann einstückig mit der Hülse 20 ausgeführt sein.The collar 22 is disposed at the setting end 24 of the sleeve 20 and may be integral with the sleeve 20.

Die Öffnung der Hülse 20 am Setzende 24 bildet einen Einblasmund 32, an den eine Düse 34 eines Verbindungswerkzeugs (nicht gezeigt) dicht angesetzt werden kann.The opening of the sleeve 20 at the setting end 24 forms a Einblasmund 32, to which a nozzle 34 of a connecting tool (not shown) can be tightly attached.

Zur Verbindung der Werkstücke 12, 14 wird, nachdem das Nietelement 18, wie in Figur 1 dargestellt ist, in die Öffnung 16 eingesetzt wurde, ein Fluid, beispielsweise Luft, unter Hochdruck in den Hohlraum 29 eingebracht.For connecting the workpieces 12, 14, after the rivet element 18, as in FIG. 1 is shown, was inserted into the opening 16, a fluid, such as air, introduced under high pressure into the cavity 29.

Hierzu wird, wie in Figur 2 dargestellt, die Düse 34 des Verbindungswerkzeugs in den Einblasmund 32 eingeführt, sodass der Hohlraum 29 vollständig geschlossen ist.For this purpose, as in FIG. 2 shown, the nozzle 34 of the connecting tool inserted into the inflation mouth 32, so that the cavity 29 is completely closed.

Nun wird unter Hochdruck ein Fluid, in den Figuren durch Punkte angedeutet, in den Hohlraum 29 gepresst.Now, under high pressure, a fluid, indicated in the figures by dots, pressed into the cavity 29.

Durch den Druck des Fluids wird die Hülse 20 des Nietelements 18, insbesondere das Schließende 26 plastisch verformt und das Nietelement 18 gesetzt. Das Schließende 26 erhält zum Beispiel eine Pilzform.Due to the pressure of the fluid, the sleeve 20 of the rivet element 18, in particular the closing end 26, is plastically deformed and the rivet element 18 is set. The closing end 26 receives, for example, a mushroom shape.

Bei der Verformung wird das Schließende 26 und der aus dem Werkstück 14 herausragende Teil des Schaftes 28 derart verbreitert, dass sie einen Hinterschnitt ausbilden, der am Werkstück 14 anliegt.During the deformation, the closing end 26 and the part of the shank 28 protruding from the workpiece 14 are widened in such a way that they form an undercut which bears against the workpiece 14.

Die Verformung und Gestalt des Hinterschnitts kann durch die Art und/oder die Geometrie des Formabschnitts 30 beeinflusst werden.The deformation and shape of the undercut can be influenced by the type and / or the geometry of the molding section 30.

In der gezeigten Ausführungsform ist der Formabschnitt 30 leichter verformbar als die übrigen Abschnitte des Schaftes 28, sodass sich der Schaft 28 im Bereich des Formabschnitts 30 verformt und weitet.In the embodiment shown, the mold section 30 is more easily deformable than the remaining sections of the shaft 28, so that the shaft 28 deforms and widens in the region of the mold section 30.

Um eine bessere Verformbarkeit des Nietelementes 18 zu erreichen, kann das Nietelement 18 vor dem Einbringen des Fluids erwärmt werden.In order to achieve a better deformability of the rivet element 18, the rivet element 18 can be heated prior to the introduction of the fluid.

Auch kann das Fluid selbst vor dem Einbringen erwärmt werden.Also, the fluid itself can be heated prior to introduction.

Auch ist es denkbar, dass der Druck und/oder die Temperatur des Fluids an die gewünschte Klemmlänge des Nietelements angepasst ist. Denn auch durch den Druck und/oder die Temperatur des Fluids lässt sich Einfluss auf die Verformung des Nietelements 18 nehmen. Zum Beispiel führt ein hoher Druck zu einer nahezu vollständigen sphärischen Verformung des Schließendes 26.It is also conceivable that the pressure and / or the temperature of the fluid is adapted to the desired clamping length of the rivet element. For even the pressure and / or the temperature of the fluid can influence the deformation of the rivet element 18. For example, a high pressure leads to a nearly complete spherical deformation of the closing end 26.

Nachdem die gewünschte Verformung des Nietelements 18 erzielt wurde, wird die Düse 34 vom Nietelement 18 entfernt, und das Fluid kann aus dem Hohlraum 29 entweichen.After the desired deformation of the rivet element 18 has been achieved, the nozzle 34 is removed from the rivet element 18, and the fluid can escape from the cavity 29.

Auch ist es denkbar, dass das Fluid durch die Düse 34, beispielsweise durch die Erzeugung eines Unterdrucks, aus dem Hohlraum 29 entfernt wird.It is also conceivable that the fluid is removed from the cavity 29 through the nozzle 34, for example by the generation of a negative pressure.

Die beiden Werkstücke 12, 14 sind nun durch das Nietelement 18 miteinander fest verbunden, wie in Figur 3 zu erkennen ist.The two workpieces 12, 14 are now firmly connected to each other by the rivet element 18, as in FIG. 3 can be seen.

Um die sichere Verbindung der Werkstücke 12, 14 durch das Nietelement 18 zu gewährleisten, kann erneut Fluid in den Hohlraum 29 des Nietelements eingebracht, das oben beschriebene Verfahren also wiederholt werden.In order to ensure the secure connection of the workpieces 12, 14 through the rivet element 18, fluid can again be introduced into the cavity 29 of the rivet element, that is to say the method described above is repeated.

Ebenfalls kann die Verbindung zwischen den beiden Werkstücken 12, 14 nachträglich angezogen werden, beispielsweise nach der Hälfte der vorgesehenen Lebensdauer der Werkstücke 12, 14. Hierzu kann das oben beschriebene Verfahren wiederholt werden, jedoch wird dabei das Fluid mit einem höheren Druck als beim vorherigen, erstmaligen Einbringen in den Hohlraum 29 des Nietelements 18 gepresst, um die Werkstücke 12, 14 wieder gegeneinander zu verpressen.Also, the connection between the two workpieces 12, 14 can be tightened subsequently, for example, after half of the intended life of the workpieces 12, 14. For this purpose, the above-described method can be repeated, however, the fluid is at a higher pressure than in the previous, first insertion into the cavity 29 of the rivet element 18 pressed to the workpieces 12, 14 again against each other to press.

Auch kann die durch das Nietelement 18 erzeugte Verbindung zwischen den beiden Werkstücken 12, 14 wieder gelöst werden, beispielsweise wenn eines der Werkstücke 12, 14 ausgetauscht werden soll. Hierzu wird, wie in Figur 4 dargestellt, die Düse 34 wieder an den Einblasmund 32 angelegt und erneut Fluid in den Hohlraum 29 des Nietelements 18 eingebracht. Der Druck des Fluids ist in diesem Fall jedoch so hoch gewählt, dass das Schließende 26 des Nietelements abreißt, wodurch der bei der Verformung erzeugte Hinterschnitt mit abgerissen wird. Auf diese Weise kann nun der verbleibende Teil des Nietelements 18 wieder aus der Öffnung 16 entfernt und die beiden Werkstücke 12, 14 voneinander getrennt werden.Also, the connection between the two workpieces 12, 14 produced by the rivet element 18 can be released again, for example if one of the workpieces 12, 14 is to be exchanged. For this purpose, as in FIG. 4 shown, the nozzle 34 is again applied to the injection mouth 32 and again introduced fluid into the cavity 29 of the rivet 18. However, the pressure of the fluid is chosen in this case so high that the closing end 26 of the rivet element breaks off, whereby the undercut produced during the deformation is also torn off. In this way, the remaining part of the rivet element 18 can now be removed again from the opening 16 and the two workpieces 12, 14 are separated from each other.

Dabei kann der Formabschnitt 30 als vorgesehene Abrissstelle dienen, wenn er entsprechend schwach ausgebildet ist.In this case, the mold section 30 can serve as an intended break-off point if it is correspondingly weak.
